Solar radiation databases

Solcast provides bankable, high quality, and low uncertainty TMY and Time Series solar irradiance data, along with monthly averages, for all continents except Antarctica. Instant sign-up and free credits to new users via the Solcast API Toolkit. Our 1-2km satellite-derived database is updated daily, extends back to 2007, with data resolutions from 5 to 60 minutes available.

OpensolarDB is a database with average global daily solar radiation data for each month of the year as measured on the ground. The uniqueness of this solar database is that it is open for everybody, open for extracting data and open for introducing data. Everybody can extract data. This extracting can be done in various ways: by downloading, doing a copy/paste on-line, by connecting to a webservice or by Flex Remote Object services (amf format). The solar radiation data in OpensolarDB are free and very accessible in many ways. OpenSolardb website
